C#

Some one gave me the below code from code project because I wanted to access a Button in my ControlModel.cs from view.aspx. But I'm not sure about declaring a varibale as globally. I already have a web control( protected Web.Controls.Button Btn;) which is in view.File.aspx.designer.cs. Is that what he meant by global variable? I mean in his code which is butctrl.

First declare one variable as object Globaly.

and write in view.cs as--

                  object b;
                  object but;
 
                  foreach(object b in this.Controls())
                  {
                        if (TypeOf(b) == Button)
                        {
                              but Button = CType(b, Button);
//      here pass but to global variable. if ur variable is butctrl then
                              butctrl=but               
                        }
                  }

Now in ControlModel.cs
u can get butctrl as ur button from view.aspx.
